VESSEL FOB CONTAINING ACIDS AND OTHER LIQUIDS.

Specification of Letters ratent.

Application flee larch 2B, 1919. Serial No. 886,864.

To all whom it may concern:

Be it known that I, WALTER HAYHURBT, a sub'ect of the King of Great Britain and Ire and, and resident of Woodlands, Accrin n, in the county of Lancaster, Englan have invented certain new and useful Improvements relating to Vessels for Containin Acids and other Liquids, of which the fofiowing is a specification.

This invention has for its ob'ect to provide an improved method for orming the joints between the tiles or the like with which acid or other li uid containers may be lined, the said material being convenient to handle and work into the joints and having very high acid resisting properties.

I haveifound that if the products resulting from the mter-action of aldehydes and ghenols, cresols and their hcmologues, be

eated until they become plastic the plastic mass being then rammed, or molded into the 'oints between the tiles linin a vessel, and if, after the moldi is comp eted, the temperature to which e jointing material is subjected, be raised say by 100 to 150 degrees Fahrenheit, and maintained for a period, then the material sets and becomes hard and acid proof, and the whole lining has the character of a one-piece lining effectually resisting penetration by the contained liquid.

My invention therefore consists in the formation of the joints between the tiles of a vessel linin b the moldi into the said 'oints of a p astic mass. obtamed'b ntly eating a product resulting from t e interaction of an aldehyde and henol, cresol, or a homolo e thereof, the w ole lining being then sub ected to increased temperature whereby the jointing material is rendered hard and inso uble.

In one convenient application of In invention, the tiles are arranged in the lining in the vessel interior and the joints between the same are filled in with plastic substance obtained by gently heating the product resulting from the interaction of formaldehydes and phenols, cresols or their homo logues. After the joints have been well filled,

the tem rature of the interior of the vessel is raise to form 100 to 150 degrees Ijarhenheit above the temperature I at which the plastic mass is formed. The jointing material sets hard and becomes insoluble to most chemical materials. The lining is then in the nature of a one-piece lining which effectually protects the material of which the vessel is made.

If desired, the jointing material may have suitable fillers such as asbestos, incoror ated therewith which serve to 've coesion to the mass when in the plastic state.

The jointing material may be subjected to any desired de es of temperature, maintalned for a erlod determined by the nature of 6216 material and the service to which it is us If desired, the vessel after the joints have been filled with the material aforesaid, may be placed under a vacuum or reduced pressure for assisting in the extraction of any solvent which ma have been em 10 ed in the production of 51o plastic pheno al ehyde mass. In like manner, the vessel may be placed under pressure for assisting or expediting the setting operation.

The accompanying drawing illustrates one convenient form of jointing in accordancewith my invention, Figure 1 being a sectional view of a lined vessel and Fig. 2 a detail view of a joint. The steel or other metal vessel "a is lined with an acid resist ing cement b 'n' which tiles 0 are bedded. The adjacent dges of the tiles are recessed or cut away provide pockets at 01 into which the .material before described is molded when in a plastic state. Finally the temperature is raised as before indicated to 1011111 the material in the pockets d to set If desired, the backing cement b may be made of the samematerial as that emplo ed at the face of the tiles. The latter are t on embedded in the lastic material which also extends right to 't e tile face.

Having now described my invention what I claim as new and desire to secure by Letters Patent is The combination with a metal vessel of a continuous lining of acid resisting cement arranged a ainst the inner surfaces of the walls and t e bottom of the vessel, a plurality of tiles embedded in the lining throughout the area thereof and positioned so as to leave a relatively narrow joint between the edges of the tiles, the side and end edges of the tiles being recessed near 5 the outer faces to provide pockets and a retaining binding of acid resisting cement molded in the pockets and having the outer face lying flush with the outer faces of the tiles and having its inner portion joined with the joints of cement between the tiles. 10

In testimony whereof I have signed my name to this specification.
